An electric dipole of moment $7.2 × 10^{−8}\; C\; m$ is placed in a uniform electric field of magnitude $2.42 \times 10^4 N C^{−1}$. Initially, the angle between the dipole and the field is zero. Then, the dipole is turned at $30^{\circ}$ with respect to the direction of the electric field. What is the potential energy stored in the dipole in the given field?
